         DAISYTEK ANNOUNCES PROPOSED OFFER TO BUY ISA INTERNATIONAL PLC
            Acquisition will Provide Platform for European Expansion


ALLEN, TEXAS (MAY 7, 2002) - Daisytek International Corporation (Nasdaq: DZTK),
a $1.2 billion wholesale distributor of computer and office supplies and
provider of marketing and demand-generation services, has announced its
intention to make a cash offer for all of the ordinary share capital of ISA
International plc (London AIM: ISA.L), one of the largest, publicly listed,
pan-European distributors of computer supplies. The cash offer will be 7.5 pence
(approximately $0.11) in cash for each ISA ordinary share, which values the
existing issued ordinary share capital of ISA at approximately Pound Sterling4.4
million (approximately $6.4 million) and is subject to a precondition relating
to finalization of audited ISA accounts. ISA shareholders will also be offered a
share alternative in unregistered Daisytek common stock.

         The ISA acquisition will provide Daisytek with an enhanced platform to
expand into Europe. The combination will bring together Daisytek's logistical
expertise, financial resources and global infrastructure with ISA's pan-European
reach, customer relationships and local knowledge.

         "The opportunity to participate in the European market is exciting for
Daisytek and we look forward to working more closely with the ISA management
team. Our goal is to be the largest supplier of computer and office supplies in
the world, and obtaining a foothold in Europe with a market-leading company such
as ISA is a major achievement in our international growth strategy," said Jim
Powell, Daisytek president and CEO.

         "Since our original preference shares investment in September 2001, ISA
has shown improved operations and an increase in sales. This partnership will
strengthen the strategic positions of both companies and will enhance our
relationship with global vendors and customers. The Daisytek-ISA team will focus
on continued operational and financial improvements, including ISA debt
reduction, and an aggressive sales and marketing strategy."

         Directors of ISA have said they intend to unanimously recommend the
offer. Daisytek has already received irrevocable commitments to accept the offer
in respect of 56.5% of ISA ordinary shares. In addition, Daisytek's existing
investment in preference shares allows it to convert into an equivalent number
of new ISA shares, as is currently outstanding, plus one.

         ISA, with annual revenues of L.361 million (approximately
$510 million) for calendar year 2001 is based in Bradford, England, with offices
and distribution centers in the United Kingdom, Ireland, Germany, France, Italy,
Norway and Sweden. In addition, ISA indirectly owns 47% of

Kingfield Heath Limited, a privately owned U.K.-based wholesaler of office

         Under the offer, ISA shareholders will also be offered a share
alternative of 0.914 shares of Daisytek restricted common stock for every 100
ISA ordinary shares held. The offer is being made in compliance with the U.K.
City Code on Takeover and Mergers. The offer is being made in the United States
pursuant to an exemption from the U.S. tender offer rules provided by Rule
14d-1(c) under the Exchange Act and pursuant to an exemption from the
registration requirements of the Securities Act of 1933 provided by Rule 802
thereunder.
